WILLIAM W. BATCHELYDER, OF NEW YRK, N. Y.

CONSTRUCTION OF VAPOR-BURNERS. Y

Specification of Letters Patent No. 25,621, vdated October 4, 1859.

To all whom t may concern:

Be it known that I, W. WV. BATCHELDER, of New York, in the county of New York and State of New York, have invented certain improvements in Burners for Vapor of Oil of Turpentine and Analogous Liquids, and that the following is a full, clear, and exact description of the principle or character which distinguishes them from all other things before known and of the usual manner of making, modifying, and using the same, reference being had to the accompanying drawings, of which- Figure 1 is a perspective view of the 'burner from behind, Fig. 2 a perspective view of the burner from the front, F ig. 3 a section through the middle of the retort and escape pipe, Fig. 4 an elevation of the fountain and pipe.

My invention consists in certain improvements in burners for the vapor of oil of turpentine and analogous liquids, described as follows:

The fountain or reservoir a and supply pipe b with the usual wick packing within are constructed and operated in the same manner as with other vapor burners. At that part of the pipe Z), which I call the retort designated by letter c, where the heat is applied for Volatilizing the oil, the passage e, turns at angles and the vapor issuing from orifice z', passes horizontally through the atmosphere into the vapor or gas pipe d, carrying with it a portion of air. This pipe curves around nearly in circular form until it rises in a straight portion 7c to form the jet m for burning the vapor. At a short distance about a quarter of an inch below the retort c, which is connected with pipe la, this pipe is pierced or tapped and a small aperture n made to allow a small jet of gas to escape the burning of which is to supply heat to vaporize the liquid in the retort. Connected with the bottom of the retort are two wire staples a', a2, the staple a nearest the gas pipe being somewhat longer than staple a2. The heating jet of gas from aperture n, plays within these wire staples and there impinges upon the bottom of the retort. The pointed wire attached to the screw 0, passes into orifice z', from behind and regulates the escape of vapor by its adjustment, this being a well known mode of regulating the passage of vapor in burners of other descriptions.

It will be seen that the end of the vapor pipe cl, which receives the stream of gas from the retort is entirely disconnected from the retort so that the resinous sediment which is always formed more or less about the orifice z', cannot pass across or spread to the gas pipe, and that by reason of the horizontal discharge from orifice z', no sediment can fall into the gas pipe.

It is obvious that if the orifice were placed over the open end of pipe d, the sediment in falling would drop into it and soon choke the gas pipe, and that to obviate this it is not necessary that the escape of the gas should be exact-ly horizontal, but I prefer the horizontal direction for other reasons. It is obvious also that' if the vapor discharged vertically upward, from the orifice the sediment would remain about and choke the orifice. It being necessary to prolong the passage of the vapor through the pipe d, and also desirable to avoid any short bends or turns in this pipe, the circular form of the pipe is that best adapted to the horizontal discharge of the vapor through the atmosphere. The form of the circle may be departed from although that best suits the case, of the horizontal discharge and other conditions required for the perfection of the burner. It is obvious also that if the end of CZ, were connected with the retort by a perforated ferrule or by a bridge piece that the sediment would spread itself when heated over the connections and to pipe al. The arrangement of the retort just back of the upright portion of the burner and the horizontal discharge of the vapor through the atmosphere at that point concentrates all the heating influences upon the vapor and the air which is to commingle with the vapor as well as the air which supplies the upward draft to the jet m, and furthermore admits of most convenient application of the regulating point attached to screw p, and altogether constitutes a most efficient cheap and simple form of burner for this purpose and one not liable to be deranged.

What I claim is- 1. Arranging the orifice of discharge z' from the retort in reference to the open end of the gas pipe d, so that the sediment from the orifice cannot fall into said pipe, nor remain about and Choke the orifice, substan* 5 tially in the manner and for the purposes Set forth.

2. I also claim the entire disconnection of the pipe d, and retort as set forth.

3. I also claim the combination of the oirn cular form of the gas pipe d, With the hori- 10 zontal discharge as Set forth.

4. I also claim connecting the retort With the ascending part of the gas pipe and near the burner as set forth.
